Explanation:

On October 31, around twelve o'clock at night, the lights were dull. It was Siberian cold and I was walking painfully under the whitish lighting of a lamppost and the retro neon lights of a convenience store in a neighborhood that was buzzing when I went to buy meat. buildings, grayish in this half-light, crumbled under the weight of sleep, while the neighborhood was still open. Its decoration was particularly macabre in tone: synthetic but very sticky spider webs adorned the porches of the terraces, pumpkin ornaments are exhibited like works of art, ... Some pushed the macabre by hanging mannequins made up in corpses. At the entrance to the neighborhood, I found the body of its owner stabbed. Frozen in place, I wondered what else awaits me. My heart was pounding, feeling a shiver of anguish. When I was removing the phone from my pocket to call my police friends, my hands were clenched in fear. An investigation was carried out to find out the causes of death. Also, I went with them so they take my words. Hopefully the murderer will be arrested to put an end to this sybilinous crime.

If a file is opened for reading and the file does not exist,what action is taken?
worty [1.4K]

Answer:

C)An error message is issued.

Explanation:

If we try to open a file for reading when that file does not exist, we will get an error message.

For example, in Java we will encounter a FileNotFoundException as in the code below:

       try {

           FileInputStream fis = new FileInputStream("myFile.txt");

           DataInputStream dis = new DataInputStream(fis);

           BufferedReader br = new BufferedReader(new InputStreamReader(dis));

           String str = null;

           while ((str = br.readLine()) != null) {

               System.err.println(str);

           }

       } catch (FileNotFoundException e) {

           e.printStackTrace();

       }

If the file myFile.txt does not exist we can expect to see an exception stack trace corresponding to FileNotFoundException.
